Light of wavelength 545 nm passes through a diffraction grating with 1.35 x103 slits/cm The diffraction pattern is observed on a screen 1.70 cm from the grating. 

a) Determine the separation distance between the adjacent maxima on the screen.

 b) A second monochromatic light illuminates the diffraction grating simultaneously. The second-order maximum of the second light falls midway between the central maximum and the first-order maximum for the first light on the screen. Determine the wavelength of the second light.
